CHAP. I. Instructions and Prescripts for the Cure of the Phthi∣sick, and Consumption of the Lungs.
WE must observe the divers states of this Disease, or the distinctive Marks which belong to it: As First, when it is meerly a Cough: Secondly, when it begins to degenerate in∣to a Phthisick or Consumption: Thirdly, when the Phthisick is consummated, or past recovery.
1. And First, as to a new Cough from what Cause soever it a∣rises, it is never free from suspicion of danger, if it happens in a Body predispos'd to a Phthisick; though in other robust Persons it be not presently to be fear'd: For if at any time it be rais'd from some great evident cause, and being without a Fever, and an indisposition of the whole Body, it proves not very trouble∣some, then it is said to be only a cold taken, and is either wholly neglected, or soon Cur'd without much ado. Again, if it be ac∣companied with a small Feaver, Thirst, and loss of Appetite, there is hope that the Blood being restor'd to its due temper, the Cough will also cease of its own accord; but if drawing in length, and not easily submitting to vulgar Remedies, it produces much Spit∣ting, and that discoloured, it ought no longer to be neglected, but must be dealt withal with a method of Cure, and fit Reme∣dies, and an exact Form of Diet: For then it may be suspected that the Lungs having receiv'd some prejudice in their Conformation do not transmit the Blood entirely, but with a deposition of the Serum, or Lympha, and often the nutritive Juice; and likewise that those humours there deposed do putrify, and consequently that by a reciprocal injury they taint the Blood, whereby it still offends the Lungs the more.
